I wasn't able to upload this on the day of October 31. Sorry
Phili's costume is of a mambabarang. A Mambabarang is a witch that can summon demons and ghost, and curse to kill. It's kind of a high level witch in our country. There's a witch that can only curse someone with just sickness, some can only summon, can cure and others can curse to kill. I found in google the reference to this costume. I forgot the link though but I think you'll know when you see it
I was planning to color this Himaruya style but I'm still learning how to do it. So maybe I'll color this some other time.
